Complex biomechanical properties of non-augmented and augmented pedicle screws in human vertebrae with reduced bone density

Abstract Background In osteoporotic bone, the quality of the bone-to-implant interface is decreased, which may lead to early implant failure. Screw anchorage can be improved by augmentation. This effect is mainly investigated with a pull-out test. To our knowledge, the effect of cement augmentation...
